Noise Survey

INERTANCE has a capability to perform the noise survey with valid noise monitor for site noise source identification as well as soundproof design. This sound survey results will be used as back ground data for noise contour map, and the sound monitor for verification purpose will be performed after finalizing the noise allocation study with soundproof.

Site noise measurement is carried out in accordance with related ISO and EEMUA 140. These guides are helpful, where noise limits have to be set and complied with in the petroleum, petrochemical and allied industries.

A free-field microphone is used for site noise measurement and the survey shall be made with sound level meters as per ANSI S1.4 Type 1. In addition, the suitable calibration has to be followed within annual basis.
